Removing duplicates [sort , uniq]

Hey Guys,
I have file which looks like this,

Contig201#numbPA
Contig1452#nmdynD6PA
dm022p15.r#CG6461PA
dm005e16.f#SpatPA
IGU001_0015_A06.f#CG17593PA

I need to remove duplicates based on the chracter matching upto '#'.

for example if we consider this..

Contig201#numbPA
Contig1452#nmdynD6PA
Contig201#numbPA
Contig1452#nmdynD6PA
dm022px15.r#CG6461PA
Contig201#Xg123
Contig1452#Xg345
dm022px15.r#PA12sy
Contig430#Pp345

I need the output to be ...

Contig201#numbPA
Contig1452#nmdynD6PA
dm022px15.r#CG6461PA
Contig430#Pp345

I know I could have used [sort infile | uniq -w9 > outfile] if the characters upto '#' were of the same length.

peace
sharat

MAKE_SOCKDFR(8) 					      System Manager's Manual						   MAKE_SOCKDFR(8)

NAME
make_sockdfr - Generates frozen route file for SOCKS server SYNOPSIS
make_sockdfr [infile [outfile] ] DESCRIPTION
make_sockdfr reads in a plain-text route file for the SOCKS server and produces a frozen route file as the output. Both arguments are optional. The default for infile is /etc/sockd.route; the default for outfile is /etc/sockd.fr. You may specify infile while omitting outfile, but you cannot specify outfile without also speficying infile. The contents of the frozen route file is essentially the memory image of the parsed input file. Using the frozen route file can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents. When the SOCKS server starts, it always looks for the frozen route file /etc/sockd.fr first. If that file is not found, it then tries to use the plain-text route file /etc/sockd.route. If you use frozen route file, you must remember to run make_sockdfr every time after you modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file. To find out the contents of a frozen route file, use dump_sockdfr. FILES
